Beschreibung
Zusammenfassung:	The present invention relates to a new process for synthesising a crystalline material comprising the zeolite MFI structure in nanocrystalline form, and which can comprise at least the following steps: i) preparing a mixture comprising at least one source of water, at least one source of a tetravalent element Y, at least one source of a trivalent element X, at least one source of an alkali cation or alkaline earth metal cation (A), and at least one organic molecule (OSDA1), wherein OSDA1 is preferably a monocyclic quaternary ammonium with the structure R1R2CycloN+, the molar composition of the mixture being:nX2O3: YO2: a A :mOSDA1 :zH2O; ii) crystallising this mixture in a reactor; and iii) recovering the crystalline material obtained.
